Imaggeo on Mondays: counting stars

Imaggeo on Mondays: counting stars

This year’s imaggeo photo contest saw humdreds of great entries. Among the winning images was a stunning night-sky panorama by Vytas Huth. In today’s post, Vytas describes how he captured the image and how the remote location in Southern Germany is one of the few (in Europe) where it is still posssible to, clearly, image the Milk Way.

I took the image in October 2015, usually the last time of the year when it is possible to see the center of the Milky Way at night. It is a single exposure 50mm, f/1.8, iso6400, 6s and it was shot in the north-eastern German lowlands. Light pollution is little there since it is the least dense populated region of Germany with lakes and forests and clean fresh air. Many other areas of Central and Western Europe are heavily light polluted, and decent shots of the Milky Way can usually only be done high up in the mountains. Light pollution has been recognised as a problem since the early 80s and its adverse effects of light pollution affect human health, animal behavior and ecosystem functions.

However, even the area where this shot was taken is not free of light pollution, which can be seen by the orange glow at the bottom of the image resulting from nearby village lights. However, a proper amount of lighting is generally unneeded, with audits suggesting between 30-60 %. This indicates that a better managing of light not only reduces light pollution but also energy waste and greenhouse gas emissions.

Last, but not least, everyone I know loves to watch the stars. Dark night skies are a cultural heritage, that man has looked upon for thousands of years, used as a calendar to prepare sowing and harvest or to navigate ships around the world’s oceans. For these reasons I believe that it is equally important to preserve dark skies as much as other elements of nature.

To put it into Bill Watterson’s words (creator of the famous comic series Calvin and Hobbes): “If people sat outside and looked at the stars each night I bet they would live a lot differently.”

Imaggeo on Mondays: Moving images – Photo Contest 2016

Since 2010, the European Geosciences Union (EGU) has been holding an annual photo competition and exhibit in association with its General Assembly and with Imaggeo – the EGU’s open access image repository.

In addition to the still photographs, imaggeo also accepts moving images – short videos – which are also a part of the annual photo contest. However, 20 or more images have to be submitted to the moving image competition for an award to be granted by the judges.

This year saw seven interesting, beautiful and informative moving images entered into the competition. Despite the entries not meeting the required number of submissions for the best moving image prize to be awarded, three were highly ranked by the photo contest judges. We showcase them in today’s imaggeo on Mondays post and hope they serves as inspiration to encourage you to take short clips for submission to the imaggeo database in the future!

During a flight over the Caliente dome of Santiaguito volcano to collect images for photogrammetry, this explosion happened. At this distance, you can clearly see the faults along which the explosion initiates, although the little unmanned aerial vehicle is shaken quite a bit by the blast.

Timelapse video of Undulatus asperitus clouds over Disko Bay, West Greenland. This rare formation appeared in mid-August at the tail end of a large storm system that brought strong winds and exceptional rainfall. The texture of the cloud base is caused by turbulence as the storm passed over the Greenland Ice Sheet. The status of Undulatus asperitus is currently being reviewed by the World Meteorological Organisation. If accepted, it will be the first new cloud type since 1951. Camera and settings: Sony PMW-EX1, interval recording mode, 1 fps, 1080p. Music: Tycho – A Walk.

Imaggeo on Mondays: a big thank you from the EGU

The past week in Vienna was a busy one! Hordes of Earth, ocean and planetary scientists came together to present, share and discuss their most recent scientific findings at the 2016 General Assembly.

The conference was a great success, with over 4800 oral and 10300 poster presentations, as well as close to a 1000 PICO presentations too! Participants at the conference could pick talks and posters from a staggering selection of over 600 scientific sessions, as well as in excess of 300 side events. The programme in 2016 was indeed rich and varied! Helping participants choose from the vast selection of science on offer, 15,000 copies of EGU Today were distributed throughout the week.

The conference was attended by 13,650 scientists from 109 countries, of which 25% were students and 53% early career scientists (under the age of 35 years). There was also a keen media presence and reporting, and thousands of visits to the webstreams as well as to GeoLog.

We thank all of you very much for your attendance and your active contribution to this great event.

We look forward to seeing you all next year! The EGU General Assembly is back from 23–28 April 2017 in Vienna, Austria.

Announcing the winners of the EGU Photo Contest 2016!

The selection committee received over 200 photos for this year’s EGU Photo Contest, covering fields across the geosciences. Participants at the 2016 General Assembly have been voting for their favourites throughout the week  of the conference and there are three clear winners. Congratulations to 2016’s fantastic photographers!

In addition, this year, to celebrate the theme of the EGU 2016 General Assembly, Active Planet, the photo that best captured the theme of the conference was selected by the judges. The winner is the stunning ‘Mirror Mirror in the sea’, by Mario Hopmann! Congratulations! Scroll to the top of this post to view Mario’s image.
